Microstructure Control and Pseudoelasticity of Ti-Nb-Ge Alloy

Microstructures and pseudoelastic behavior of Ti-Nb-Ge alloys were investigated in order to correlate the pseudoelasticity and microstructure together with martensite transformation. XRD results and transmission electron microscope revealed that stress-induced martensitic transformation takes place during room temperature deformation in the present alloys. Recrystallization heat treatment of the present alloy displayed pseudoelastic behavior to be prominent. It is concluded that the pseudoelastic behavior of a metastable-β Ti-Nb-Ge alloy is correlated to the stress-induced martensite transformation.
